DeathMatch level, players appear as Cyberdemons; just start CM.BAT and begin a network/modem/serial game without changing the Map Warp and Misc Settings or adding other WADs. After you finish playing run DELCM.BAT to erase the level.

Use CM.BAT every time you play.

Although CyberMatch may coexist peacefully with other wads in your DOOM folder, I strongly recommend using a clean DOOM 2.

And, a word about the level itself. Although I built it in a relatively short time, this map is the result of many years of computer and gaming experience for me. While constructing it was't always a pleasant occupation (there were moments when I felt ruined and frustrated), I now find myself very happy and content with the result - I see this not merely as a WAD, I see it more as a product of my imagination and creative thought. I did my best.
